/* These allow debugging flags to be passed into Glade via the GLADE_DEBUG

   recompiling Glade. Currently the only options supported are:
     'warnings'   - will cause Glade to abort() on any WARNING messages.
                    This only works with GTK 1.1.x.
     'messages'   - causes Glade to output debugging messages (though you must
                    configure Glade with --enable-debug to use this.
     'properties' - will cause Glade to create all widget properties on
		    start-up, and output info about them to stdout.
   To use these, set GLADE_DEBUG to the option strings, with each option
   separated by a ':'. e.g. export GLADE_DEBUG='warnings:messages'. */
